Water quality - Determination of volatile organic compounds in water - Method using headspace solid-phase micro-extraction (HS-SPME) followed by gas chromatography-mass spectrometry (GC-MS) (ISO 17943:2016)

ISO 17943:2016 specifies a method for the determination of volatile organic compounds (see Table 1). This comprises, for example, halogenated hydrocarbons, trihalogenated methanes, gasoline components (such as BTEX, MTBE, and ETBE), naphthalene, 2-ethyl-4-methyl-1,3-dioxolane, and highly odorous substances like geosmin and 2-methylisoborneol in drinking water, ground water, surface water, and treated waste water, by means of headspace solid-phase micro-extraction (HS-SPME) followed by gas chromatography-mass spectrometry (GC-MS). The limit of determination depends on the matrix, on the specific compound to be analysed, and on the sensitivity of the mass spectrometer. For most compounds to which this International Standard applies, it is at least 0,01 µg/l. Validation data related to a concentration range between 0,02 µg/l and 2,6 µg/l have been demonstrated in an interlaboratory trial. Additional validation data derived from standardization work show applicability of the method within a concentration range from 0,01 µg/l to 100 µg/l of individual substances. All determinations are performed on small sample amounts (e.g. sample volumes of 10 ml).

Wasserbeschaffenheit - Bestimmung flüchtiger organischer Verbindungen in Wasser - Verfahren mittels Headspace-Festphasenmikroextraktion (HS-SPME) gefolgt von der Gaschromatographie und Massenspektrometrie (GC-MS) (ISO 17943:2016)

Diese Internationale Norm legt ein Verfahren zur Bestimmung von flüchtigen organischen Verbindungen fest (siehe Tabelle 1). Darin eingeschlossen sind z. B. Halogenkohlenwasserstoffe, Trihalogenmethane, Benzininhaltsstoffe (wie BTEX, MTBE und ETBE), Naphthalin, 2-Ethyl-4-methyl-1,3-dioxolan und geruchsintensive Stoffe, wie Geosmin und 2-Methylisoborneol in Trink-, Grund-, Oberflächenwasser und behandeltem Abwasser, die mittels Headspace-Festphasenmikroextraktion (HS-SPME) gefolgt von Gaschromatographie und Massenspektrometrie (GC-MS) bestimmt werden. Die Nachweisgrenze ist abhängig von der Matrix, der zu analysierenden spezifischen Verbindung sowie von der Empfindlichkeit des Massenspektrometers. Bei den meisten Verbindungen innerhalb des Anwendungsbereichs dieser Internationalen Norm ist die Nachweisgrenze mindestens 0,01 µg/l. In einem Ringversuch wurden die auf einen Konzentrationsbereich zwischen 0,02 µg/l und 2,6 µg/l bezogenen Validierungsdaten nachgewiesen. Aus der Normungsarbeit abgeleitete zusätzliche Validierungsdaten zeigen die Anwendbarkeit des Verfahrens innerhalb eines Konzentrationsbereichs von 0,01 µg/l bis 100 µg/l der einzelnen Stoffe. Alle Bestimmungen werden an kleinen Probenmengen (z. B. Probenvolumina von 10 ml) durchgeführt.
Die Anwendbarkeit des Verfahrens auf weitere, in dieser Internationalen Norm nicht ausdrücklich genannten Verbindungen oder auf andere Wasserarten ist möglich. Sie muss jedoch für jeden Einzelfall nachgewiesen werden.

Qualité de l'eau - Détermination de composés organiques volatils dans l'eau - Méthode utilisant une micro-extraction en phase solide (MEPS) de l'espace de tête suivie d'une chromatographie en phase gazeuse-spectrométrie de masse (CG-SM) (ISO 17943:2016)

L'ISO 17943:2016 spécifie une méthode pour la détermination des composés organiques volatils (voir Tableau 1). Cela comprend, par exemple, la détermination des hydrocarbures halogénés, des trihalométhanes, des composants des carburants (tels que les BTEX, le MTBE et l'ETBE), du naphtalène, du 2-éthyl-4méthyl-1,3-dioxolane et de substances fortement odorantes comme la géosmine et le 2-méthylisobornéol, dans l'eau potable, les eaux souterraines, les eaux de surface et les eaux usées traitées, par micro-extraction sur phase solide (MEPS) de l'espace de tête suivie d'une chromatographie en phase gazeuse avec détection par spectrométrie de masse (CG-SM). La limite de la détermination dépend de la matrice, du composé à analyser et de la sensibilité du spectromètre de masse. Pour la plupart des composés auxquels l'ISO 17943:2016  s'applique, elle est d'au moins 0,01 µg/l. Les données de validation relatives à une plage de concentration située entre 0,02 µg/l et 2,6 µg/l ont été démontrées dans un essai interlaboratoires. Des données de validation supplémentaires tirées de travaux de normalisation montrent une applicabilité de la méthode pour une plage de concentration allant de 0,01 µg/l à 100 µg/l des substances individuelles. Toutes les déterminations sont réalisées sur de petites quantités d'échantillon (par exemple, des volumes d'échantillon de 10 ml).
Cette méthode peut être applicable à d'autres composés non explicitement couverts par l'ISO 17943:2016 ou à d'autres types d'eau. Il est néanmoins nécessaire de démontrer son applicabilité dans chaque cas.

Kakovost vode - Določevanje hlapnih organskih spojin v vodi - Metoda headspace mikroekstrakcije na trdni fazi (HS-SPME) v kombinaciji s plinsko kromatografijo/masno spektrometrijo (GC/MS) (ISO 17943:2016)

Ta mednarodni standard določa metodo za določevanje hlapnih organskih spojin. To zajema npr. halogenirane ogljikovodike, trihalogen metane, bencinske aditive (kot so BTEX, MTBE in ETBE), naftalen, 2-etil-4-metil-1,3-dioksolan in snovi z izrazitim vonjem, kot sta geosmin in 2-metilisoborneol, v pitni vodi, podtalnici in površinskih vodah z metodo headspace mikroekstrakcije na trdni fazi (HS-SPME) v kombinaciji s plinsko kromatografijo/masno spektrometrijo (GC/MS). Meja določevanja je odvisna od matrice, specifične spojine za analizo in občutljivosti masnega spektrometra. Pri večini spojin, za katere velja ta mednarodni standard, znaša ta meja vsaj 0,01 μg/l. Podatki o validaciji, ki se nanašajo na razpon koncentracije med 0,02 μg/l in 2,6 μg/l, so bili prikazani z mednarodnim medlaboratorijskim poskusom. Dodatni podatki o validaciji iz standardizacijskega dela kažejo uporabnost metode v razponu koncentracije od 0,01 µg/l do 100 µg/l za posamezne snovi. Vse določbe izhajajo iz majhnih vzorčnih količin (npr.vzorčni volumen 10 ml). Ta metoda velja za druge spojine, ki niso izrecno zajete v tem mednarodnem standardu, ali za druge vrste vode. Vendar je treba preveriti uporabnost te metode za vsak primer.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
